udev ships with gudev integrated. systemd used to ship with gudev integrated but in a rare moment of splitting it was moved out to a separate project, and the recipe for that is now in meta-oe. This means that something that depends on gudev fails to build if the init system is changed, so the gudev recipe should be moved from meta-oe to oe-core.
Merged in oe-core c6d37fc47f7ee637a069d3225e294d181e588a0e.
